is it possible to convert back outlet toilet plumbing to down outlet?

we are doing a bathroom remodel in our loft - which is in a 1917 building that was renovated in the mid-1990s.

we had picked out a toilet we liked and then our contractor told us that we need to have a back outlet toilet (not necessarily a wall-mounted one, but back outlet specifically)... and as many of you know, the selections are minimal. we are not interested in a wall mounted toilet at all.

so my question - is it a huge ordeal to have the plumbing converted so that it can accomodate a regular "down outlet" toilet? our pipes need to be moved anyway as our toilet area is being moved several feet from its current placement - so we already do need to have plumbing work done.

Sounds like this is the time to do it since you are going to be redoing the drains anyway. One positive thing is you will have many more choices in toilets. I would urge you to seriously consider the Toto line.

If your contractor says you need a wall outlet, I would ask him if it's possible to open up the wall below your unit and the floor to move the piping around.
If it's only $3000 to move the piping, then it may be a good idea.

As my dad used to say, "Anything is possible if you have enough time and money." Installing a floor mount toilet could take a lot of both items, depending on how the building is constructed and exactly where you want the toilet.
